  • Microbiology Holding Time Study for Water Quality Assessments - Florida Dept. of Environmental Protection, Bureau of Laboratories, 2013. This report describes a study conducted by the Florida Department of Environmental Protection (DEP) from 2008-2011 to investigate the effects of increasing holding time beyond 8 hours to 24 or 30 hours prior to laboratory analysis of fecal coliform, Escherichia coli, and enterococci. (PDF file size 2.0 MB)
  • Bathing Beach Fecal Indicator Depth Study - Florida Dept. of Environmental Protection, Bureau of Laboratories. 2012. This report describes a two-year study of two bathing beaches (Carrabelle Beach and Mashes Sands Beach) in North Florida investigating the influence of spatial sampling along the beach front (three locations plus a control station) and distance from the beach as identified by ankle, knee, and waist sampling on indicator bacteria (fecal coliform and enterococci) recoveries, and the potential impacts of sampling multiple locations and multiple depths on the identification of Impaired Waters of the State. (PDF file size 1.26 MB)
  • Methods of Hester-Dendy Multiplate Sampler Deployment - Florida Dept. of Environmental Protection, Bureau of Laboratories. 2006. A review of different deployment techniques for Hester-Dendy multiplate samplers, specifically a comparison between floating platforms and submerged blocks. (PDF file size 350 kb)
  • Statistical Analysis of Surface Water Quality Specific Conductance Data - Florida Dept of Environmental Protection, Bureau of Labs, Biology Section. The Triennial Review Committee of Florida Department of Environmental Protection (FDEP) requested the Biology Section to evaluate scientific evidence to support or reject the need to revise the Surface Water Quality Standard for Specific Conductance. This document was written in response to that request. (PDF file size 2.25 MB) Appendix 3 Data
  • MSIIT Guidance Document - Technical Guidance Document for Conducting the Florida Department of Environmental Protection’s Protocols for Determining Major-Seawater-Ion Imbalance Toxicity (MSIIT) in Membrane-Technology Water-Treatment Concentrate, 73 pp. May 2004. Documents the development of a set of protocols for determining major-seawater-ion toxicity in membrane-technology water-treatment concentrate, or reject water. (PDF file size 520 KB)
  • Salinity Tolerance SETAC Poster - Low-Salinity Toxicity Tests with the Mysid Shrimp (Americamysis Bahia) and Drinking Water Facility Concentrates: Is Salinity Stress an Issue? (SETAC Poster)
  • Fla. Dept. Environmental Protection, Bureau of Laboratories. 1995.
    Protocols for determining Major-seawater-ion toxicity in membrane-technology water-treatment concentrate. 26 pp. [unpublished report] [This document contains the results of a study to determine methods for identifying toxicity to marine animals resulting from an 'imbalance' of the major seawater ions. The report includes the rationale for the method, the results of the study, and the methods allowing one to determine whether toxicity in a sample results solely from major seawater ion imbalance, solely from 'other' toxics, or from a combination of the two causes.
    The zip file contains 2 files; the RO report in .pdf, the ion calculation spreadsheet in Excel format.
    RO SOPs can be found in the list of Internal Biology SOPs. Search by Category and choose Toxicity-RO Methods.
